Where is placed the solar system in the universe?
Right in the center. Actually, from any point of view it would look as if we were in the center of the Universe.Right in the center.

How can Earth be located at the center of the observable universe if you accept the cosmological principle?
According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.According to the cosmological principle, from ANY point it would seem as if we are at the center of the Universe.
What is the purpose of the pistil?
The purpose of the pistil is for the female reproductive organ of the flower. The pollen would enter the pistil and start the reproductive process.
What happens when a pistil is removed?
If the pistil of the flower, which is the female portion of the flower, is removed the flower would no longer be able to produce seeds. Removal of the pistil would be highly detrimental as it would be highly invasive and damaging to the flower and would decrease a plant's ability to reproduce.
Do roses have petals?
No. There are petalless flowers. They reproduce by having the wind release their pollen.different classifications of flowers according to the presence or absence of their parts:Complete flowers are made up of calyx, corolla, stamens, and a pistil or pistils (the four "regular parts").Incomplete flowers lack one or more of the four regular parts of a complete flower as in all of the Fagaceae (oak family), Betulaceae (birch family) and Juglandaceae (walnut family).Perfect flowers have both stamens and pistils, but not necessarily sepals or petals.Imperfect flowers lack either stamens or pistils, and may or may not have sepals or petals.Naked flowers are without petals (apetalous) or sepals (asepalous) as in Zantedeschia spp. (calla lily).Apetalous flowers lack petals as in Elaeagnus pungens (silverthorn), Hydrangea spp. and Cornus florida (flowering dogwood).Staminate (male) flowers have a stamen or stamens, but no functional pistils.Pistillate (female) flowers have a pistil or pistils, but no functional stamens.
What is the name of the point in the middle of the circle?
That would be the center.
What does the pistel do on a flower?
Pistil or the female reproduction structure is the innermost whorl, located in the center of the flower. Often vase-shaped, the pistil consists of three parts: the stigma, the style and the ovary.
Can the chord touch the center point?
No, it cannot. If it did, it would be called the diameter.
What is the earths center of gravity?
Its a theoretical point, if you threw it in the air spinning, it would rotate around this point.
Why would the pistil and stamen of flowers adapted to be different lengths?
So that they are able to survive in harsh conditions. For example, mountains where it is windy, the pistil and stamen of flowers would be longer compared to the flowers on lower ground.
In some plants the pistils don't form until a few days after the stamens do how might this plant keep a plant from self-pollinating?
For a flower to be pollinated, pollen from an anther (which is located at the top of the stamen) needs to reach a stigma (at the top of the pistle.) Some plants are genetically capable of pollinating themselves if their own pollen reaches their own stigma; some plants are not capable of self pollination under any circumstances. For plants that can genetically self pollinate, but would prefer not to, they can avoid this by having their pistil and pollen/stames mature at different times. If the stamens mature first, the pollen will be dispersed by animals or wind or whatever dispersal mechanism it relies on. Then by the time the pistil is ready to be pollinated, there is no pollen left in that flower to land on the stigma.
Does a diameter always sometimes or never passes through the center of the circle?
The diameter ALWAYS passes through the center of a circle. If it stopped at the center point, it would be a radius, and if it didn't do either, it would be chord.
